• Resumen

  • A simulated female reproductive system behaves almost like the real thing over 20 days. Julie Kim's team has hooked up tissue from the ovaries, uterus, cervix and fallopian tubes, as well as the liver, which makes compounds that help to transport hormones. The tissues responded to hormones made by the mini ovary: oestrogen in the first two weeks, then progesterone for the next two weeks. In the first half of the cycle, eggs grew and burst out of the ovary--mimicking ovulation. Tiny hairs in the fallopian tube began to beat faster, as if to waft the egg along, while cells in the uterus proliferated.
